This is a holiday weekend, so the usual vast array of free film offerings at the local museums and stages is a bit truncated for Thanksgiving. But even though it’s a lean cornucopia, there are a few old movies you can see in and around town this week, with no cash required.

Go to a museum on any given weekend in Washington, and chances are you’ll find a free movie to barge in on. This weekend, though, there are a lot more cinematic offerings with no ticket required, and many of them aren’t even decades old.

It’s a safe bet that the most popular movie at the box office this weekend will be the one about the video game character who breaks out of his virtual world and explores the rest of what the arcade has to offer.
